In known ventilation cans of this type, the lid-shaped can part and the socket-shaped can part are made of plastic, and these parts are fixed against relative rotation by means of a metal insert hexagonal piece. The socket-shaped can portion is provided with a sealing piece to prevent rainwater from entering the inside of the container from the ventilation opening through the gap between the can portion and the container. Since the lid-like can protrudes from the outer wall of the container in use, there is a risk of unintentional interference with the lid-like can or the influence of the mounting force when attaching the ventilation can to the container.

According to the present invention, the support pin located on the radially inner side of the lid-shaped can is fitted into the boss of the socket-shaped can that is fixed to the container, and is freely rotatably supported. Even if the can is interfered with, the lid-shaped can part rotates freely, so the sealing piece in the accommodation groove of the socket-shaped can part is not affected by the interference. Furthermore, since the sealing piece is spatially separated from the attachment means, the sealing piece will not be affected even if an attachment force is applied to the attachment means or the attachment means is deformed due to attachment to the container. , maintaining an unaltered sealing function.

In FIG. 1, a lid 4 as a lid-shaped can part of a ventilation can configured as a bell-shaped case has a labyrinth wall 15 and an inner central hollow support pin 12. A boss 13 of an insertion socket 5 serving as a socket-shaped portion of the ventilation can is rotatably supported on the support pin 12. The boss 13 of the bayonet socket 5 with the labyrinth walls 38 and 39 has an inner collar 40 which is radial to the socket axis 7-7 as a central axis and which
0 fits into the circumferential groove 41 of the support pin 12. The radial divisions 19 of the groove 41 thus serve as stops, and the lateral divisions 20 of the collar 40 serve as counterstops for axially fixing the boss 13 to the support pin 12. The center opening of the boss 13 is opened at 42 through the vertical slit 17 of the support pin 12.
A ventilation passage 14 connected to a labyrinth chamber 16 is formed at this point. An annular gap 43 between the lid rim 44 and the labyrinth wall 39 connects the labyrinth chamber 16 to the atmosphere. The longitudinal slots 17 of the support pin 12 constitute the free ends of this support pin 12 as elastic tongues 18, which are elastically compressed when the collar 40 passes over them.
The end of the boss 13 on the outside with respect to the lid 4 is likewise slit in the axial direction, so that an elastic tongue with an inverted hook-shaped projection 9 at the end serves as an attachment means for attaching the ventilation can to the container. 8 is formed. The protrusion 9 together with the protrusion 58 on the labyrinth wall 39
It serves to axially fix the ventilation can in a ventilation opening of a housing to be sealed, for example a gearbox housing of an automatic transmission. Tongue piece 8 and labyrinth wall 39
The boss 13 is further provided with an outer circumferential groove 10 as a sealing piece accommodating groove, and an annular sealing piece 11 is inserted into this groove 10. Lid 4 is boss 13
Since it is rotatably supported by the lid 4, even if the lid 4 receives unintended external interference, it will freely rotate and avoid the interference, so the sealing piece 11 will not be affected by this interference. Also, when fixing the ventilation can to a container, even if the elastic tongue 8 is bent radially inward at the inverted hook-shaped projection 9 in order to pass through the ventilation opening of the container, the sealing in the outer circumferential groove 10 remote from this can be prevented. Piece 11 is not affected by this.

３４から始まるねじ穴４８をもつている。 In the second embodiment according to FIG. 3, the plug-in socket 5 is rotatably supported via its boss 25 on a support pin 24 of a metal nut piece 23. The nut piece 23 is attached to the cylindrical fitting hole 2 of the hollow pin-shaped protrusion 29 of the lid 4 by means of a mounting pin 27 on the opposite side.
8 in the direction of the socket axis 7-7 so as not to be lost. The nut piece 23 has a hexagonally designed collar 30 in its intermediate region, which is fitted in a corresponding fitting hole 31 in the projection 45 of the lid 4 in a manner that prevents relative rotation. In the direction of socket axis 7-7, boss 2
5 is fixed to the nut piece 23 on the one hand by a collar 30 and on the other hand by a small annular ridge 26 on the support pin 24. The ventilation passage of the plug-in socket 5 is formed by an axial notch 21 eccentric to the central support opening 22 of the boss 25. Cylindrical projection 4 connected to boss 25
6 has radial labyrinth walls 38 and 39 which together with a projection 45 of the lid 4 form an annular gap 47 connecting the ventilation channel 21 with the labyrinth chamber 16 of the lid 4. In the flow path between the annular gap 47 and the labyrinth chamber 16 there is also a labyrinth wall 15 of the lid 4 . The connection between the atmosphere and the labyrinth chamber 16 is provided by an annular gap 43 between the labyrinth wall 39 and the lid rim 44.
It is carried out by. The end face 32 of the insertion socket 5 on the side opposite to the lid 4 has a socket axis 7.
An annular groove 36 coaxial with respect to -7 is formed, and an annular sealing piece 37 is fitted into this annular groove 36. The distance 33 between the end face 32 and the lid 4 is smaller than the distance 35 between the end face 34 of the nut piece 23 on the side opposite to the lid 4 and the lid 4. Support pin 24 has a threaded hole 48 starting from end face 34 thereof.

ることはない。 A dowel bolt 52, which is fastened in a manner not shown in the bottom of the housing 51, has at its upper end an externally threaded portion 56 which passes through a ventilation opening 55 in the lid 49 with an annular clearance; Screw hole of support pin 24 of nut piece 23 (attachment means)
It is screwed into 48. At this time, the end surface 34 of the support pin 24 is located on the upper surface of the lid 49 and has a ventilation opening 55.
It abuts against a central clamping surface 57 having a radial slit-like recess as a passage communicating between the recess 21 and the recess 21 . In this case as well, the lid 4 can be rotated freely, so
The sealing piece 37 within the annular groove 36 is not affected by external interference with the lid 4. In addition, the ventilation can is placed in the container 5.
0, when the lid 4 is screwed onto the male threaded part 56 of the retainer bolt 52 fixed to the container, the insertion socket 5 and therefore the sealing piece 37 are
Since it is simply brought closer to the lid 49 of the container 50 without being rotated relative to it, it is not adversely affected by the mounting rotational force.
